The world famous Whisper power filter updated for the 21st century. The Whisper Ex20 aquarium power filter offers a host of modern conveniences and advanced filtration capabilities to keep your aquarium clean, clear and healthy. Benefits and features include:

Great flow rate, quiet, timestrips are handy, biological filter works well

Cons:

Prepackaged filter cartridges, seats crooked easily

I have this filter (EX20 version) in a 10gal tank, with some dirty fish. It does an excellent job keeping the water clear and creates good current. It has a very good flow rate in this size tank. The only thing I wish it could accomodate was biobags so I could fill them with carbon + zeolyte more easily. I do slice open the carbon inserts and refill them with zeolyte+carbon mixture but it would be nice if there were a fill-it-yourself option too.

Overall though, I am extremely pleased with the water quality. The biological media has gathered quite a farm of the helpful bacteria to help remove ammonia, and my levels have never risen above .02 (even with a goldfish). I do 2-3 gallon water changes every 10-14 days or so. Other than that, it's maintenance free!

Cons:

Died after 4 months

Can't revise my original review, so here's an update. Died tonight, and of course I don't have a 4 month old receipt... "quality" modern manufacturing like everything else.
